The algae blooms suck oxygen out of the water and degrade water clarity, which makes life difficult for other marine creatures such as cod and herring.

Another source is shore homes, like this one, that drain their waste directly into the sea. Thousands of such vacation homes ring the shoreline in nations like Sweden.
